Brickwork and Garden Walls in Northampton: What's Possible and What It Costs

A well-built garden wall does more than mark a boundary. It holds back a slope, creates planting space where there was none, adds structure to a flat garden, and — done properly — lasts for decades without much thought. Brickwork is one of those things that looks simple from the outside but goes wrong quickly when it's rushed, underspecified, or handed off to someone who doesn't really understand it. This guide covers the types of brickwork we build for Northampton homeowners, what different projects typically cost, when you need planning permission, and why keeping brickwork in-house matters more than most people realise.

Types of Brickwork We Build

Not all garden brickwork is the same. A low decorative wall along the front of a property is a very different job to a retaining wall holding back a metre of soil on a sloped plot. Here's a breakdown of the main types we handle.

Boundary and Garden Walls

These are the most common requests — a wall along the front or rear boundary of a property, or dividing sections of a garden. They can be single-skin or double-skin construction depending on the required height and structural need. Coping stones along the top finish the wall, shed water, and add a clean edge. Matching existing brick is often possible if you're extending or repairing rather than building fresh.

Retaining Walls

If your garden slopes — or you want to create level terraces from uneven ground — a retaining wall holds the difference. These carry genuine structural load, so the specification matters: foundation depth, wall thickness, rebar reinforcement in taller structures, and drainage behind the wall to prevent water pressure building up. A poorly built retaining wall will move, crack, or fail. We handle the groundworks and drainage as part of the same project — no handoffs, no gaps.

Raised Beds and Planters

Brick-built raised beds are a popular feature in garden redesigns. They add height, define planting zones, and work well alongside porcelain paving or gravel finishes. We build them freestanding or integrated into a wider patio layout. Internal lining and drainage are built in from the start — not an afterthought.

Garden Steps

Brick steps linking different levels of a garden — between a patio and lawn, or between terraces — are both practical and good-looking. We build them with consistent rise and tread dimensions, proper foundations, and often pair them with adjacent walling or retaining structures on the same project.

Repointing and Brick Repairs

Existing walls deteriorate over time. Mortar washes out, bricks crack, frost damage opens up joints. Repointing replaces weathered mortar and stabilises the wall before it gets to the point of rebuilding. We also repair spalled or damaged bricks and rebuild collapsed or leaning sections — useful when you want to restore rather than replace entirely.

Brick Types and Mortar Choices

The most common brick for garden walls in Northampton is a standard facing brick — available in a range of colours from buff and red to blue engineering brick. Engineering bricks are denser and more resistant to frost and moisture, which makes them a good choice for walls with high water exposure — retaining walls, low boundary walls close to ground level, or anything in a damp garden.

Reclaimed bricks suit older properties or projects where matching existing materials matters. They vary in quality, so it's worth checking they're sound before building with them.

Mortar mix matters as much as brick choice. Harder mortars — high cement content — can actually cause problems with older or softer bricks, as the mortar won't flex and the brick takes the stress. For repointing especially, matching the original mortar type is important to avoid accelerating damage. We'll advise on the right spec for your project and the materials already in place.

Cost Ranges for Brickwork in Northampton

Brickwork pricing varies with height, length, specification, and access. These figures give a realistic ballpark for Northampton projects in 2024 — they're not quotes, but they're honest.

• Low boundary wall (up to 600mm, single skin): £150–£250 per metre run, including foundations and coping
• Standard garden wall (600mm–1.2m, double skin): £250–£400 per metre run
• Taller boundary or screen wall (1.2m–1.8m): £350–£550 per metre run depending on specification
• Retaining wall (up to 1m retained height): £400–£650 per metre run — more if engineered drainage or reinforcement is needed
• Raised planter beds: £600–£1,500+ depending on size and complexity
• Brick garden steps (per step): £150–£300 per step, including foundation and landing
• Repointing: £30–£60 per square metre of wall face

Site access, ground conditions, and whether excavation is needed all affect the final figure. A sloped site, poor access, or a high-spec brick will push costs upward. We provide free, detailed quotes after a site visit — no assumptions, no surprises.

Planning Permission: What Northampton Homeowners Need to Know

Most garden walls in Northampton don't require planning permission — but there are height limits you need to stay within.

Under permitted development rules, you can build a wall up to 1 metre high adjacent to a highway (including paths and roads), and up to 2 metres high elsewhere on your boundary without needing permission. Go above those heights and you'll need to apply. The same applies if your property is listed, or if your home is in a conservation area — restrictions are tighter and you should check before starting work.

For homeowners in Northampton, Daventry, and Towcester, planning is handled by West Northamptonshire Council. You can also check your project against national guidance via the Planning Portal before you get in touch with the local authority.

If you're unsure whether your wall needs permission, raise it with us during the quote stage. We deal with these questions regularly and can point you in the right direction.

Structural Considerations for Retaining Walls

Retaining walls deserve more thought than decorative ones. The soil behind the wall exerts horizontal pressure — and that pressure increases with height and with water saturation. A wall that holds back a shallow planting bed is a different proposition to one retaining a full metre of garden on a sloped plot.

Key factors for a properly specified retaining wall include:

• Foundation depth: Retaining walls need deeper footings than freestanding ones. The foundation needs to sit in stable, undisturbed ground.
• Wall thickness and construction: Taller walls need more mass — double-skin construction or reinforcement.
• Drainage: Without drainage behind the wall, water pressure builds up after rain and puts enormous force on the structure. We install a drainage layer and outlet points as standard on retaining projects.
• Tie-backs or reinforcement: On larger structures, additional engineering may be needed. We'll tell you upfront if that's the case.

Our groundworks capability means we handle excavation, drainage, and foundations ourselves — no subcontracted groundwork team showing up separately. That matters for scheduling and for getting the foundation right before any brickwork starts.

How Brickwork Fits Into Wider Landscaping Projects

The best garden projects combine materials well. Brick walls work alongside porcelain paving, natural stone, gravel, and timber — and we frequently build walling as part of a larger patio or garden redesign. A raised bed at the edge of a new patio. Steps linking two levels with matching brick. A low front boundary wall that frames a new resin driveway.

Because we handle brickwork and landscaping under the same roof, projects like this are planned from the start rather than bolted together from separate contractors. Materials are chosen to work together, groundwork is sequenced properly, and the finish is consistent across the whole project.

Why In-House Brickwork Matters

A lot of landscaping contractors subcontract brickwork. They'll manage a driveway or patio themselves but bring in a bricklayer separately for any walling. That creates real problems: scheduling gaps, quality control issues, and situations where no one is clearly responsible when something doesn't look right.

We do brickwork in-house. The same team that digs the foundations and sets out the paving builds the walls. That means consistent standards across the whole project, no waiting around for a third party to become available, and one point of contact from start to finish.

Frequently Asked Questions

How high can I build a garden wall without planning permission in Northampton?

Up to 1 metre high adjacent to a road or footpath, and up to 2 metres on other boundaries. These are permitted development limits. If your property is listed or in a conservation area, different rules apply — check with West Northamptonshire Council before starting work.

How long does a brick garden wall last?

A properly built wall with appropriate foundations, good mortar, and a decent coping should last 50 years or more with minimal maintenance. Frost damage, subsidence, and water ingress are the main causes of early deterioration — all of which are addressed by getting the specification right from the outset.

Do I need building regulations approval for a garden wall?

For most residential garden walls, building regulations approval isn't required. Retaining walls over a certain height — particularly those adjacent to a building or public area — may be a different matter. We'll flag anything relevant during the quote stage.

Can you match brickwork to my existing house?

Often, yes. Matching brick depends on what's available — older properties may use bricks that aren't manufactured any more, in which case reclaimed stock is the best option. We'll look at your existing materials and give you an honest assessment of what's achievable before any work starts.

Can brickwork be built at the same time as a new patio?

Yes — and that's usually the best approach. Building walls and paving as part of the same project means the groundwork is done once, materials are coordinated, and the finished result looks considered rather than piecemeal. We regularly combine paving, walling, and planting into a single project.
